MOON by Simaudio 610LP Phono Preamplifier

This sophisticated phono preamplifier draws its engineering philosophy from Simaudio's reference-grade 810LP, employing a dual-mono architecture with fully balanced differential circuitry. The result is a purist approach to vinyl playback that prioritizes signal integrity and sonic transparency without unnecessary complexity.

Built with meticulously selected components and a bespoke power supply architecture, the 610LP delivers uncompromised audio performance. Its oversized power delivery system—integrated directly into the main chassis and shielded within precision-engineered 14-gauge steel—effectively suppresses AC interference, ensuring pristine signal purity throughout your vinyl listening experience.

Engineered as an accessible interpretation of Simaudio's flagship 810LP, the 610LP distills reference-grade technology into a meticulously crafted phono stage. Its dual-mono, fully balanced architecture pairs custom components with an oversized power supply—featuring a toroidal transformer, pi-type filtering, and multi-stage voltage regulation housed in precision steel—to achieve performance rivaling battery-powered designs. Comprehensive DIP-switch configurability enables adjustment of gain, impedance, capacitance, and EQ curves, positioning controls directly in the signal path for minimal sonic compromise. This flexibility, combined with exceptional overload margin, accommodates virtually any cartridge and pressing with transparency and musicality.

• An overdimensioned power supply that produces a DC signal with a noise floor of 140dB related to 1.0V, DC-100kHz
• The voltage control of the power supply includes i²DCf (independent inductive DC filtering); there is. There is one inductor for each component of the integrated circuit type (DAC, Op-Amp, etc.) in the signal path of the audio switching path audio signal path; a total of 24 stages
• Selectable equalizer curves for both the RIAA and IEC standards
• Customized parts include metallized polypropylene film capacitors with very small tolerances-1%.
• 4-layer printed circuit boards with pure copper routes for a much shorter signal path.
  This results in greater sonic accuracy and dramatically improved signal-to-noise ratio
• Power supply with a "pi-type" filter consisting of 40,000uF capacity and double choke
  induction

Reviews & Awards

• "Even the most delicate pieces of classical music, the noise floor is always in the recording, with tape hiss from the master coming through, not the electronics. Personally, this is one of the true benefits of a great solidstate phonostage — the absence of noise." – Jeff Dorgay, TONEAudio
